Description

Technical Field

[0001] This utility model relates to the technical field of gas treatment equipment, specifically to a dedicated dehydration and dehumidification device. Background Technology

[0002] In numerous industrial sectors such as chemical, electronics, and food processing, as well as in special environments like warehousing and laboratories, strict control of gas humidity is crucial for ensuring product quality, stable equipment operation, and environmental suitability. For example, during lithium battery production, excessively high ambient humidity can cause electrode materials to react with moisture, affecting battery performance and safety. In precision instrument storage environments, humid gases can easily lead to rust on metal components and short circuits. Existing dehumidification equipment often suffers from low processing efficiency and high energy consumption. On the one hand, single dehumidification methods are insufficient to meet the high-precision humidity requirements under complex operating conditions; on the other hand, the equipment lacks real-time monitoring and intelligent control mechanisms, failing to flexibly adjust operating parameters based on changes in gas flow and pressure, resulting in energy waste and unstable dehumidification effects. Therefore, developing equipment with high-efficiency dehumidification capabilities and intelligent control functions has become an urgent industry need. To address this, a dedicated dehumidification device is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a dedicated dehydration and dehumidification device to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dedicated dehydration and dehumidification device, comprising a main body, an air inlet and an air outlet disposed on the main body, wherein a gas flow sensor and a humidity sensor are disposed at both the air inlet and the air outlet; characterized in that: the main body of the device is provided with a dehydration chamber communicating with the air inlet, a dehumidification chamber having one end communicating with the air outlet and the other end communicating with the dehydration chamber via a pipe, and a circulation duct having one end connected to the inlet of the dehydration chamber and the other end connected to the outlet of the dehumidification chamber for guiding gas that has not met the predetermined requirements back to the dehydration chamber for circulation processing; the dehydration chamber is provided with a dehydration component for preliminary dehydration processing of the incoming gas, the dehumidification chamber is provided with a dehumidification component for further dehumidifying the gas after preliminary dehydration, and the circulation duct is provided with a circulation fan for driving the gas to flow in the circulation duct and a flow regulating valve for regulating the gas flow rate through the circulation duct; the flow sensor, humidity sensor, dehydration component, dehumidification component, circulation fan and flow regulating valve are electrically connected to a controller for controlling the operation of the device.

[0005] Preferably, the dehydration assembly includes at least one set of centrifugal dehydration devices and a condensation dehydration device disposed downstream of the centrifugal dehydration devices; a gas guide plate is provided between the centrifugal dehydration devices and the condensation dehydration devices to guide the gas flow.

[0006] Preferably, the centrifugal dehydration device includes a servo motor and a centrifugal dehydration tank driven by the servo motor; the inner wall of the centrifugal dehydration tank is provided with spiral guide protrusions for guiding the flow path of gas during the centrifugal dehydration process.

[0007] Preferably, the condensation and dehydration device includes a condenser tube for condensing gas into water droplets and a water collection tank located below the condenser tube for collecting the water droplets.

[0008] Preferably, the centrifugal dehydration tank and the water collection tank are provided with interconnected drain pipes at the bottom, and the drain pipes are provided with programmable valves that are electrically connected to the controller.

[0009] Preferably, the dehumidification assembly includes a dehumidification wheel rotatably installed in the dehumidification chamber, a servo motor that drives the dehumidification wheel to rotate and is electrically connected to the controller, and a dehumidifier filled in the dehumidification wheel; the dehumidification wheel is divided into a regeneration zone and a dehumidification zone.

[0010] Preferably, the regeneration zone is connected to a hot air supply device for regenerating the dehumidifier via a pipe, and a cooling device is provided between the pipe connecting the dehumidification zone and the air outlet.

[0011] Preferably, the main body of the device is also provided with a drain outlet connected to a drain pipe.

[0012] Preferably, the air outlet is also equipped with a programmable valve.

[0013] The beneficial effects of this utility model are as follows: Through a dual dehydration and dehumidification mechanism, the dehydration chamber performs preliminary dehydration on the gas, and the dehumidification chamber performs deep dehumidification on the gas after preliminary dehydration, ensuring that the dryness requirements are met. This method is adaptable to different humidity conditions and improves the overall dehumidification effect. Through the setting of the circulating air duct, the gas that does not meet the standard is guided back to the dehydration chamber from the outlet of the dehumidification chamber for reprocessing, forming a closed-loop system, completely eliminating residual moisture, ensuring that the output gas meets the dryness requirements, and avoiding energy waste caused by the direct discharge of gas that does not meet the standard. Through the controller, the flow sensor and humidity sensor on the air inlet and outlet collect the dynamic parameters of the gas in real time, automatically adjust the operating status of the dehydration component, the dehumidification component and the circulating air duct, dynamically adjust the humidity changes, avoid over-processing or under-processing, and improve the reliability of the equipment.

[0014] By incorporating a centrifugal dehydration device, the system prioritizes the removal of suspended liquid water from the gas. The condensation dehydration device then processes the residual water vapor, preventing liquid water from directly impacting the subsequent dehumidification wheel and solving the problem of wheel clumping in traditional equipment under high humidity conditions. The spiral guide protrusions of the spiral structure force the gas to spiral along the barrel wall, extending the path by 2-3 times and increasing the dehydration time. Combined with the centrifugal force of the high-speed rotation of the centrifugal dehydration barrel, the droplets impact the barrel wall more efficiently, increasing the dehydration rate. At the same time, this structure also avoids disordered gas collisions, reducing the risk of secondary evaporation of water droplets. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Participation Figure 1-2 As shown in this embodiment, a dedicated dehydration and dehumidification device is characterized by: including a device body 1, an air inlet 2 and an air outlet 3 disposed on the device body 1, wherein a gas flow sensor 4 and a humidity sensor 5 are respectively disposed at the air inlet 2 and the air outlet 3; characterized in that: the device body 1 is provided with a dehydration chamber communicating with the air inlet 2, a dehumidification chamber having one end communicating with the air outlet 3 and the other end communicating with the dehydration chamber through a pipe, and a device having one end connected to the inlet of the dehydration chamber and the other end connected to the outlet of the dehumidification chamber for guiding gas that has not met the predetermined requirements back to the dehydration chamber for circulation processing. The circulating air duct 6; the dehydration chamber is equipped with a dehydration component 7 for preliminary dehydration of the incoming gas, and the dehumidification chamber is equipped with a dehumidification component 8 for further dehumidification of the gas after preliminary dehydration. The circulating air duct 6 is equipped with a circulating fan 61 for driving the gas to flow in the circulating air duct 6 and a flow regulating valve 62 for regulating the flow rate of the gas flowing through the circulating air duct 6; the flow sensor 4, humidity sensor 5, dehydration component 7, dehumidification component 8, circulating fan 61 and flow regulating valve 62 are electrically connected to a controller 9 for controlling the operation of the equipment.

[0022] The controller 9 is preset with a gas humidity threshold and a flow rate threshold. The main body 1 of the equipment serves as the overall frame. High-humidity gas enters the dehydration chamber from the air inlet 2. During the process, the gas flow sensor 4 and humidity sensor 5 accurately detect the flow rate and humidity data of the incoming gas in real time and transmit the collected information to the controller 9 in a timely manner. After the gas undergoes preliminary dehydration treatment by the dehydration component 7, it is then transported to the dehumidification chamber through a pipeline. The gas undergoes further deep dehumidification by the dehumidification component 8. After dehumidification, the humidity sensor 5 at the outlet gas 3 detects that the gas humidity is lower than the humidity threshold. The controller 9 controls the flow regulating valve 62 to open and starts the circulating fan 61 to guide the gas back to the dehydration chamber for reprocessing until the standard is met. The qualified gas is directly discharged from the air outlet 3.

[0023] Through a dual dehydration and dehumidification mechanism, the dehydration chamber performs preliminary dehydration on the gas, while the dehumidification chamber performs deep dehumidification on the gas after preliminary dehydration, ensuring that the dryness requirements are met. This method adapts to different humidity conditions and improves the overall dehumidification effect. Through the setting of the circulating air duct 6, the gas that does not meet the standard is guided back to the dehydration chamber from the outlet of the dehumidification chamber for reprocessing, forming a closed-loop system to completely eliminate residual moisture, ensuring that the output gas meets the dryness requirements and avoiding energy waste caused by the direct discharge of gas that does not meet the standard. The controller 9 collects the real-time dynamic parameters of the gas from the flow sensor 4 and humidity sensor 5 on the air inlet 2 and air outlet 3, and automatically adjusts the operating status of the dehydration component 7, the dehumidification component 8 and the circulating air duct 6, dynamically adjusting humidity changes to avoid over-treatment or under-treatment and improve equipment reliability.

[0024] In one embodiment, the dehydration assembly 7 includes at least one set of centrifugal dehydration devices 71 and a condensation dehydration device 72 disposed downstream of the centrifugal dehydration devices 71; a gas guide plate is provided between the centrifugal dehydration devices 71 and the condensation dehydration device 72 to guide the gas flow; the centrifugal dehydration device 71 includes a servo motor 711 and a centrifugal dehydration tank 712 driven by the servo motor 711; the inner wall of the centrifugal dehydration tank 712 is provided with a spiral guide protrusion 7121 for guiding the gas flow path during centrifugal dehydration; the condensation dehydration device 72 includes... A condenser tube 721 for condensing gas into water droplets and a water collection tank 722 located below the condenser tube 721 for collecting water droplets; the centrifugal dehydration tank 712 and the water collection tank 722 are provided with interconnected drain pipes 10 at their bottoms, and the drain pipes 10 are provided with programmable valves 11 electrically connected to the controller 9; the main body of the equipment 1 is also provided with a drain outlet 12 connected to the drain pipes 10; the condenser tube 721 is made of copper, stainless steel or glass, and adopts a spiral structure to increase the contact area with the gas and improve the condensation effect; the condenser tube 721 is refrigerated by a compressor.

[0025] During operation, high-humidity gas enters the centrifugal dehydration device 71. The controller 9 adjusts the speed of the servo motor 711 based on the flow and humidity data transmitted by the flow sensor 4 and the humidity sensor 5. The speed is increased when the flow is high to increase centrifugal force, and the speed is reduced when the flow is low to reduce energy consumption. The servo motor 711 drives the centrifugal dehydration tank 712 to rotate at high speed. The high-humidity gas is guided by the spiral guide protrusion 7121 to form a spiral upward airflow. The liquid water is thrown to the inner wall by the centrifugal force and falls to the bottom of the tank. It flows out of the drain outlet 12 of the main body 1 through the drain pipe 10 at the bottom of the tank. The gas that has been initially dehydrated enters the condensation dehydration device 72 after being rectified by the guide plate. The gas contacts the tube wall of the condenser tube 721 and is cooled to below the dew point temperature. The water vapor condenses into water droplets and falls into the water collection tank 722 below. The water collection tank 722 flows out of the drain outlet 12 of the main body 1 through the drain pipe 10. The dry gas is output to the dehumidification chamber.

[0026] By setting up the centrifugal dehydration device 71, the suspended liquid water in the gas is removed first. The condensation dehydration device 72 then processes the residual water vapor, avoiding direct impact of liquid water on the subsequent dehumidification wheel 81, thus solving the problem of wheel clumping in traditional equipment under high humidity conditions. The spiral structure of the spiral guide protrusion 7121 forces the gas to spiral along the barrel wall, extending the path by 2-3 times and increasing the dehydration time. Combined with the centrifugal force of the high-speed rotation of the centrifugal dehydration barrel 712, the droplets impact the barrel wall more efficiently, increasing the dehydration rate. At the same time, this structure also avoids disordered gas collision and reduces the risk of secondary evaporation of water droplets.

[0027] In one embodiment, the dehumidification assembly 8 includes a dehumidification wheel 81 rotatably mounted in the dehumidification chamber, a second servo motor 82 driving the dehumidification wheel 81 and electrically connected to the controller 9, and a dehumidifier 83 filled in the dehumidification wheel 81. The dehumidification wheel 81 is divided into a regeneration zone 811 and a dehumidification zone 812. The regeneration zone 811 is connected to a hot air supply device 84 for regenerating the dehumidifier 83 via a pipe. A cooling device 85 is provided between the pipe connecting the dehumidification zone 812 and the air outlet 3. The hot air supply device 84 is an electric heating wire type hot air supply device. The dehumidifier 83 is silica gel, activated alumina, or molecular sieve. The cooling device 85 is an air-cooled cooling device. The second servo motor 82 drives the dehumidification wheel 81 to rotate via a belt, and the rotation speed can be dynamically adjusted by the controller 9.

[0028] After preliminary dehydration, the gas enters the dehumidification zone 812 of the dehumidification rotor 81 through a pipe. The gas comes into full contact with the desiccant 83 filled in the dehumidification rotor 81. The desiccant 83 adsorbs the moisture in the gas, thus achieving dehumidification. After dehumidification, the gas enters the cooling device 85 for cooling and is finally discharged through the outlet 3. At the same time, under the control of the controller 9, the servo motor 82 drives the dehumidification rotor 81 to rotate slowly at a set speed, so that the dehumidification zone 812 is in continuous contact with the humid gas to perform dehumidification.

[0029] As the dehumidification impeller 81 rotates, when the dehumidification zone 812, which has reached saturation with adsorbed moisture, rotates to the regeneration zone 811, the hot air supply device 84 is activated, supplying high-temperature hot air into the regeneration zone 811. The high-temperature hot air comes into full contact with the saturated desiccant 83, evaporating and carrying away the adsorbed moisture in the desiccant 83, thus restoring the dehumidification capacity of the desiccant 83. Furthermore, the hot air supply device 84 only regenerates the desiccant 83 that has rotated to the regeneration zone 811, significantly reducing energy consumption compared to heating and regenerating the entire dehumidification system. Simultaneously, the regeneration zone 811 and the dehumidification zone 81... 2. Isolation via pipelines prevents secondary moisture absorption of the gas. After the regeneration process, this area re-enters the dehumidification zone 812 as the dehumidification wheel 81 rotates, continuing its dehumidification work. This cycle repeats continuously, ensuring the continuous and stable operation of the dehumidification component 8. Synchronizing regeneration and dehumidification significantly improves overall dehumidification efficiency and avoids the drawbacks of traditional dehumidification equipment requiring shutdown for replacement or regeneration of the dehumidification medium. Simultaneously, the servo motor 82 is electrically connected to the controller 9, allowing precise control of the dehumidification wheel 81's rotation speed based on actual humidity requirements, thus flexibly adjusting the dehumidification capacity. This intelligent control method adapts to different environmental humidity requirements, ensuring the dehumidification system always operates at high efficiency, improving the equipment's applicability and reliability.

[0030] In the operation of this invention, high-humidity gas enters the centrifugal dehydration device 71 in the dehydration chamber through the air inlet 2, and the servo motor 711 drives the centrifugal dehydration tank 712 to rotate at high speed.

[0031] High-humidity gas is guided by the spiral guide protrusion 7121 to form a spiral upward airflow. Liquid water is thrown to the inner wall by centrifugal force and falls to the bottom of the barrel. It flows out of the drain outlet 12 of the main body of the equipment through the drain pipe 10 at the bottom of the barrel. The gas that has been initially dehydrated enters the condensation dehydration device 72 after being rectified by the guide plate. The gas contacts the tube wall of the condenser tube 721 and is cooled to below the dew point temperature. Water vapor condenses into water droplets and falls into the water collection tank 722 below. The water collection tank 722 flows out of the drain outlet 12 of the main body of the equipment through the drain pipe 10. The dried gas is output to the dehumidification chamber.

[0032] The rotational speed of the servo motor 711 can be monitored in real time by the flow sensor 4 and humidity sensor 5 at the air inlet 2, and the data is transmitted to the controller 9. The controller 9 controls the rotational speed of the servo motor 711; when the flow rate and humidity are high, the rotational speed is increased; when the flow rate and humidity are low, the rotational speed is decreased, thus controlling energy consumption.

[0033] After initial dehydration, the gas enters the dehumidification zone 812 of the dehumidification rotor 81, where it comes into full contact with the desiccant 83. The desiccant 83 adsorbs the moisture in the gas, achieving deep dehumidification. After being cooled by the cooling device 85, the dehumidified gas is then controlled by the controller 9 to open the programmable valve 11 and exit from the outlet 3.

[0034] As the dehumidifying wheel 81 rotates, the desiccant 83 that has absorbed moisture to the point of saturation rotates to the regeneration zone 811. The hot air supply device 84 delivers high-temperature hot air to the regeneration zone 811, causing the moisture in the desiccant 83 to evaporate and restore its dehumidification capacity. The regenerated desiccant 83 then re-enters the dehumidification zone 812 as the dehumidifying wheel 81 rotates, continuing to participate in the dehumidification work.

[0035] The humidity sensor 5 at the air outlet 3 monitors the humidity of the output gas in real time. If the humidity does not meet the predetermined requirements, the controller 9 controls the programmable valve 11 on the air outlet 3 to close, and opens the flow regulating valve 62 and the circulating fan 61 leading to the circulating air duct 6, so that some of the substandard gas is guided back to the dehydration chamber through the circulating air duct 6 for further processing until the humidity requirements are met.

[0036] The controller 9 controls the programmable valve 11 on the drain pipe 10 to open or close according to the preset program or the drainage volume of the centrifugal dehydration tank 91 and the condensation dehydration device 72, so as to ensure that the water generated during the dehydration process can be discharged in time.

[0037] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
